The application is understood to have a separate user interface for accessing the storage status log 56 saved on the base station 62 . There are other embodiments, however, where the base station 62 includes a direct terminal and user interface from which the storage statuses 46 and the storage status log 56 may be accessed.
- the aircraft data storage status may be useful to a variety of entities within the flight operations environment. Specifically, there is an administrator 64 for a service provider, e.g., the entity responsible for the setup and configuration of the system 42 that maintains the various user accounts established for accessing the storage status log 56 . There may also be an administrator 66 for the airline. Those entities responsible for providing multimedia content may also utilize the storage status log 56 to better manage the data upload/deletion process from the line replaceable units 44 , including a media service 68 and a content distribution service 70 .
- the present disclosure also contemplates the base station 62 generating alerts when certain conditions are met, such as when usage is over a threshold percentage of the total capacity. These notifications may be generated through the aforementioned administrative interface, whether through a separate application or directly with a terminal of the base station 62 . Other embodiments contemplate e-mail notifications that are sent to select users. These features are intended to help airlines and content service providers manage the transfer of data, and ensure that there is sufficient storage onboard the aircraft 10 to deliver new content.
- each line replaceable unit 44 provides a storage status 46 , which includes the line replaceable unit identifier 58 , the usable storage space value 48 , and the occupied storage space value 50 .
- the usable storage space value 48 may be provided for each partition.
- one physical drive may be dedicated for operational software (e.g., Secure Digital High Capacity—SDHC cards), while another physical drive may be dedicated for media data and/or content data (e.g., solid state drives—SSDs).
- the occupied storage space value 50 is delineated or broken down according to the constituent data types noted earlier, including multimedia data, content data, software data, and temporary files.
- the storage status 46 may indicate x number of bytes for multimedia data, y number of bytes for software data, and so forth.
- temporary files is understood to refer to the files that are preserved between system reboots.
- the occupied storage space value 50 of the storage status 46 is updated at the completion of any data operation.
- One type of data operation is a data loading event, including foreground or background loading with the content loader 38 , light media loading using a universal serial bus or other portable disk drive, as well as wireless data loading via satellite, Wi-Fi or cellular modalities. If the data operation is interrupted before completion due to a loading error, connectivity loss, or other like reasons, the size of the partially loaded data is reflected in the occupied storage space value 50 .
- Another data operation also includes a data installation event, such as when updates to an executable software application, or uploads of digital certificates takes place.
- Yet another type of data operation is data production, which occurs when an avionics system or application generates data files or log files for subsequent transfer. Such data is understood to remain persistent in the storage device between power cycles. Again, the occupied storage space value 50 is updated when such new data is saved. Removal of data from the storage device of the line replaceable unit 44 also constitutes a data operation. The removal may occur as a result of an avionics system or application commands the removal of data from storage for cleanup.
- the status retrieval interface 72 is connected to a status database 74 , which stores each of the storage statuses 46 provided by the line replaceable units 44 for further processing, as will be described more fully below.
- the data storage monitor 54 may further include a status aggregator 76 that is connected to the status database 74 and retrieves each of the storage statuses 46 to generate the storage status log 56 .
- the storage status log 56 is generated in response to a Weight on Wheel (WoW) event, e.g., when the aircraft 10 lands, if a new line replaceable unit 44 has been added, or if the storage status 46 of a particular line replaceable unit 44 has changed since the last time the storage status log 56 was generated.
- the storage status log 56 is understood to include the aircraft identifier, along with a timestamp (including the date) of when it was generated.
- the data storage monitor 54 includes a ground side system interface 78 that is connectible to the base station 62 .
- the generated storage status log 56 as well as the storage status logs 56 collected in the status database 74 , are downloaded to the base station 62 , and the ground side system interface 78 establishes the communications link by which this is achieved.
- Various communications modalities may be implemented by the ground side system interface 78 , including wired and wireless types.
- the cellular modem 43 may be used, in which case the ground side system interface 78 includes a cellular module that controls the cellular modem 43 to establish the wireless data communications link over the cellular network to the base station 62 .
- the cellular connection may be activated in response to the weight on wheels (WoW) event.
- the satellite module 33 may also be used.
- the storage status log 56 may be relayed to the base station 62 manually, via a maintenance interface. An external storage device is connected the data storage monitor 54 , which is then physically taken to the base station 62 and connected thereto.
- the downloaded storage status log 56 is retained in the data storage monitor 54 until receipt of a confirmation that a successful transfer to the base station 62 has been completed.
- the storage status log 56 may be retained for fifty flight legs, though this is by way of example only and not of limitation. Any other suitable lifespan for the storage status log 56 to reside on the data storage monitor 54 may be substituted.
- the older storage status logs 56 may be sequentially deleted as new storage status logs 56 are generated, once the archive limit has been reached.
- the data storage monitor 54 may be separate from the content loader interface 40 that is used to connect the content loader 38 and load new content. However, as weight allowance and space onboard the aircraft 10 is at a premium, the data storage monitor 54 may be integrated with the content loader interface 40 . In such embodiments, the maintenance interface may provide additional information once the content loader 38 is connected. More particularly, the most recent storage status 46 for the target line replaceable unit 44 may be presented, including the line replaceable unit identifier 58 , the timestamp 55 of when the storage status 46 was recorded, the usable storage space value 48 , and the occupied storage space value 50 .
- the maintenance interface can indicate whether the operation will complete, or not be completed due to insufficient storage space.
- Content loaders 38 that connect via a wireless link may likewise provide a warning when there is insufficient storage space.
- the block diagram of FIG. 5 shows additional details of the base station 62 .
- There is an air side system interface 80 that is the counterpart to the aforementioned ground side system interface 78 , and connects to the same, over a wired connection or a wireless connection as discussed above.
- the air side system interface 80 receives the storage status log 56 and/or the storage statuses 46 , and are saved to a storage status database 82 .
- the base station 62 includes a variety of interfaces to the data in the storage status database 82 , including a management interface 84 , an application interface 86 connects to external/remote applications, and an alarm 88 that generates and sends/communicates notifications when certain conditions are met.
- the management interface 84 is understood to permit direct access to the storage status database 82 .
- storage status logs 56 from a plurality of aircraft 10 in a fleet may be stored on the base station 62 , and a hierarchical menu system may be provided that first requests the selection of a particular aircraft.
- a hierarchical menu system may be provided that first requests the selection of a particular aircraft.
- Once the aircraft 10 is selected there may be an additional selection of one or more line replaceable units 44 for which the storage status logs 56 are to be accessed. Within each line replaceable unit 44 , there may be multiple partitions and multiple physical and logical volumes, so each of these may be selectable to obtain storage statuses 46 .
- the most recent storage status log 56 for the selected line replaceable unit 44 is presented, though this is by way of example only and not of limitation.
- Historical data may also be viewed, so there may be an input element by which a time period for viewing may be selected.
- the individual storage status logs 56 from different times may be retrieved for presentation, and structured according to the data type (media, content, software, temporary files).
- the typical aircraft 10 may have numerous line replaceable units 44 with data storage capabilities, so it is contemplated that multiple line replaceable units 44 can be treated and viewed as a group.
- One application for this feature is to view the seatback unit line replaceable unit 44 c.
- There may potentially be hundreds of identically configured terminals/line replaceable units 44 and so it is possible to group these by model, cabin class, and so forth.
- the management interface 84 may additionally show and highlight the maximum, minimum, and mean value for each of the total capacity and the current occupied space for each data type.
- the application interface 86 may be used to connect external or remote applications to the base station 62 , and present the storage status logs 56 in the manner discussed above.
- the most current aircraft storage status can be provided to applications that are used for preparing data packages, following their respective workflow procedures. Access to the base station 62 through the application interface 86 may be restricted, and only permitted after validating with a username/password combination or the like.
- the storage status logs 56 downloaded to the base station 62 may be utilized for planning data uploads to the various line replaceable units 44 , and so may be queried when performing administrative tasks.
- the present system 42 also contemplates the generating of notifications when various over-capacity, or near over-capacity conditions materialize.
- the base station 62 therefore includes the alarm 88 , which monitors the data in the storage status database 82 and notifies designated message subscribers either upon logging in through the management interface 84 or the application interface 86 , or via e-mail, i.e., the alarm generates and communicates notifications in accordance with contact information for the message subscribers. Once the notification is generated, a requirement to acknowledge the notification may be enforced.
- the conditions under which the notifications are generated may be defined in a set of rules 90 .
- the notification may be generated when the occupied space for multimedia content is greater than a predefined size.
- Still another rule may be to generate the notification when the occupied storage space value 50 of a group of line replaceable units 44 is more than a predefined percentage of the usable storage space value 48 .
- notifications based on other tracked conditions are possible.
- One contemplated notification is generated when a storage status log 56 has not been received from a given aircraft 10 for over fourteen days, or any other specified time period.
- the foregoing rules 90 are presented by way of example only and not of limitation. Those having ordinary skill in the art will readily recognize other possible rules that may be set, depending on the particular needs of the administrator.
